The people changing the meaning are the ones claiming victimhood, or assigning blame for the use, of the changed word.
The starting definition applies today, and to the current circumstances. So no, it hasnt freaking changed. You are assigning guilt and a racial (im)morality to a word that is by definition generic.
Or if you want to claim its racial you are appropriating it from its base culture.
The statues I am referencing are the 54th Mass. That was destroyed because they fought in the civil war. Because the numbnuts destroying stuff couldnt be bothered to find out it was an all black regiment that fought for the north. But you know they are racist so the monument had to be destroyed.
Point is ignoring the facts and assigning false attributes to subjects is maybe even more regressive than if it was actually negative. Why fight for your freedom if idiots are just going to assume your race anyway? Why use correct or "correct" words if people are just going to condemn it anyway.
If you want real meaningful change you have to start with the truth. And when it comes to these particular histories it's pretty easy to tell. As it is you are assigning guilt and wrong where there is none. That alienates people and weakens your message. It says you dont want to have a real conversation, you want to have your pre determined conversation where everyone else is already wrong.
